Darleen Online via Amazon offers the Taseyar Therapeutic Grade Aromatherapy Essential Oils Set for $16.99. Coupon code "YNUIL6KN" cuts it to $10.99. With free shipping for Prime members, that's $3 under the lowest price we could find for a similar set, although we saw it for a buck less in May. The set contains lavender, tea tree, eucalyptus, peppermint, lemongrass, and sweet orange essential oils in 10ml bottles.
